Apply for Landmark Design Review

Landmark staff, in coordination with the Landmark Preservation Commission and the Lower Downtown Design Review Commission, perform design review for all projects that require building permits for properties locally designated as historic landmarks or inside locally designated historic districts. Design review ensures that these projects preserve the properties’ key historic character-defining features and qualities.

Next Steps: Review, Approval, and Inspections

Staff Review, Revision, and LPC or LDDRC Presentation

Quick Review (for eligible projects):

A - Landmark staff will evaluate the completeness of your application. If necessary, staff will provide comments or request revisions.

B - If an application is found to be complete and meets the design guidelines, Landmark staff will issue an approval within a few business days.

Administrative Review (for eligible projects):

A - Landmark staff will evaluate the completeness of your application and perform a preliminary design guideline evaluation, generally within 10 business days. If necessary, staff will provide comments or request revisions.

B - If an application is found to be complete and meets the design guidelines, landmark staff will issue an approval within a few business days. Projects that are approved will be issued a certificate of appropriateness.

C- If a project cannot be approved administratively, landmark staff will provide comments as to how it may be revised to meet the design guidelines or will let you know if it must be reviewed by the LPC or LDDRC. 

LPC or LDDRC Review:

The Landmark Preservation Commission (LPC) reviews projects on individual landmarks and properties in historic districts except properties in the Lower Downtown Historic District, which are reviewed by the Lower Downtown Design Review Commission (LDDRC). Projects that require LPC or LDDRC review include:

  • All additions that add more than 900 square feet or add more than 40% square footage to existing above grade square footage, whichever is less
  • Projects readily visible from public vantage points, except fences and minor site work that meets the design guidelines
  • All roof-top additions with visibility from public vantage points, including enclosed and open space
  • All new construction, including new primary structures, tandem houses, and new detached Accessory Dwelling Units (ADUs),
    • Exception: One-story garages that clearly meet design guidelines and are not visible from public vantage points do not require LPC or LDDRC review
  • Changes to character-defining or visible doors, windows, porches and other historic features
  • Major changes to historic materials
  • Comprehensive sign plans, projecting shaped signs and other signs that are not subject to administrative review as delineated in Chapter 6(PDF, 1MB) or the Lower Downtown Historic District Guidelines(PDF, 15MB), depending on which applies
  • Demolition of all primary structures, portions of a contributing structure, or contributing accessory structures
  • Improvements to all city-owned property located in a historic district or an individual landmark site
  • Projects determined by landmark staff to not meet the design guidelines

Process for LPC Design Review
Process for LDDRC Design Review

LPC or LDDRC review will result in one of the following:

  • Approved - Landmark staff will issue a certificate of appropriateness within a few business days
  • Approved with conditions - projects must submit the requested adjustments to the final construction drawings to landmark staff before a certificate of appropriateness will be issued.
  • Continued - projects must provide additional information as requested by the LPC or LDDRC, and must return to the LPC or LDDRC for approval.
  • Denied - projects must go before the LPC or LDDRC again with a revised submittal that addresses the LPC's or LDDRC's comments.

Certificate of Appropriateness

Once the project has been approved administratively or by the LPC or LDDRC, landmark staff will issue a certificate of appropriateness and stamp the drawings.

The certificate of appropriateness and stamped drawings must be included with plans and materials submitted to Development Services when applying for building or zoning permits. If drawings submitted for a building or zoning permit vary in any way from the stamped drawings issued by landmark staff, the permit drawings will need to be revised or the landmark stamped drawings will need to be revised. If drawings submitted for a building or zoning permit vary substantially from drawings approved by staff or LPC or LDDRC, the project may need to return to the LPC or LDDRC for approval. During the inspections process, the completed project must match the work shown on the landmark-approved stamped drawings. 

Please coordinate with landmark staff if any changes need to be made to the project’s design during permitting or construction.

Landmark Inspections

What to expect from your Landmark inspection:

  • The Landmark inspector will check to see if the work complies with the Denver Zoning Code, the Landmark Certificate of Appropriateness (COA) and the approved set of Landmark plans. 
    • NOTE: Any changes made after your plans have been approved  must be submitted for review and approval again. Changes made without Landmark approval will cause your inspection to be denied.
    • If you have questions about Landmark inspections for your project, please schedule a "Landmark Pre-Construction Meeting"

Landmark inspection tips:

  • Changes to design, dimensions, and/or materials (including trim work, windows, doors, etc.) will require an additional review and approval from Landmark.
  • Landmark must approve the removal, replacement, or infill of doors and windows.
  • If required by zoning, make sure there aren't any missing or dead landscaping.
  • Make sure the types of materials you've selected are allowed to be used.
    • Examples of materials not allowed: compressed artificial wood, T-111 siding, skim-coat or two-coat stucco systems, siding or trim with faux-wood grain, and vinyl windows.
  • Make sure all work complies with the Denver Zoning Code.
  • Make sure to obtain all required Landmark approvals, as well as building and/or zoning permits. 
  • Make sure the approved plans show:
    • the locations of any exterior building penetrations,
    • new AC units, fences, or site work that may require a zoning permit (e.g. planter boxes over 12” in height),
    • exterior lighting,
    • installation of a new or replacement fence, and
    • any hardscaping and site work.

NOTE: Some work does not require a building and/or zoning permit unless the building is located in a historic district or has been designated as an individual landmark site. See Denver Building Code Section 130.3: Exempted Work for such exceptions (2, 5 and 23).
